Vodacom the circus of the year

Vodacom is the most *********** Company with the most *********** staff in the world. We have a business account that we have had for 4 years and never missed a payment. Three months ago we sent an instruction to have the debit order changed. i have since received 3 emails from red premium back office (staff member Betty) confirming the change has been made, yet for the last 3 debits the old account has still been debited. Last week the phones were cut due to non - payment. I got hols of collections who apologised profusely and guaranteed that the very next day the debit order would be processed through the correct bank account. The debit order was processed as promised but once again through the incorrect bank account. Are these people ********, or do they just not care what they say because they dont understand what they are doing, but probably getting paid huge salaries to ***** up time and time again. Voaacom needs to catch a huge wake up or lose customers on an ongoing basis
